John Vorhaus writes about writing:

So that would seem to leave us with a pretty clear choice, wouldn’t it? Write, and improve; or don’t write, and don’t improve.

Why is it not that simple?

Because the forces of evil are arrayed against the desire to write. And the biggest evil of all is the need to be good. Burdened by the unrealistic expectation of all quality all the time, we often find that we just can’t write at all.
